Varroa drop after vaping.

[Mlfbah]

I'm after treating some of my maisemore nucs with the InstantVap. How long does it take for the phoretic varroa to all drop to the bottom board after vaping with oxalic acid? Would they all be dead after 24 hours or over the course of a few days? I want to check the count before moving the trays I've made onto other nucs for their treatment, and if the count is high I'd come back after more brood has hatched out and treat again.

24 hours.
With a nuc if I have a count of 10 or more I vape another three times at five day intervals

That's brilliant, thanks. I wasn't really sure what my threshold was going to be, so great to have a number to make my decision against.
